Abutilon plant named ‘Oosttrump’

ABSTRACT

A new and distinct cultivar of  Abutilon  plant named ‘Oosttrump’, characterized by its compact, upright to outwardly spreading and weeping plant habit; freely branching habit; dark green-colored leaves; freely flowering habit; and pale yellow-colored flowers.

Botanical designation: Abutilon hybrid.

Cultivar denomination: ‘Oosttrump’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Abutilonplant, botanically known as Abutilon hybrid, and hereinafter referred toby the name ‘Oosttrump’.

The new cultivar is a product of a planned breeding program conducted bythe Inventor in Venlo, The Netherlands. The objective of the breedingprogram was to develop new compact Abutilon cultivars with attractiveflower coloration.

The new cultivar originated from a cross-pollination made by theInventor during the summer of 2003 of the Abutilon megabotanicumcultivar Kentisch, not patented, as the female, or seed, parent with anunnamed selection of Abutilon hybrid, not patented, as the male, orpollen, parent. The new cultivar was discovered and selected by theInventor as a flowering plant within the progeny from thiscross-pollination in a controlled environment in Venlo, The Netherlandsduring the spring of 2004.

Asexual reproduction of the new cultivar by terminal cuttings in DeKwakel, The Netherlands since October, 2004, has shown that the uniquefeatures of this new Abutilon are stable and reproduced true to type insuccessive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Oosttrump have not been observed under allpossible environmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature and light intensitywithout, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Oosttrump’. These characteristics incombination distinguish ‘Oosttrump’ as a new and distinct cultivar:

-   -   1. Compact, upright to outwardly spreading and weeping plant        habit.    -   2. Freely branching habit.    -   3. Dark green-colored leaves.    -   4. Freely flowering habit.    -   5. Pale yellow-colored flowers.

Plants of the new Abutilon can be compared to plants of the femaleparent, the cultivar Kentisch. In side-by-side comparisons conducted inVenlo, The Netherlands, plants of the new Abutilon differed from plantsof the cultivar Kentisch in the following characteristics:

-   -   1. Plants of the new Abutilon were more freely branching than        plants of the cultivar Kentisch.    -   2. Plants of the new Abutilon and the cultivar Kentisch differed        in flower color as plants of the cultivar Kentisch had yellow        and brown-colored flowers.

Plants of the new Abutilon can be compared to plants of the male parentselection. In side-by-side comparisons conducted in Venlo, TheNetherlands, plants of the new Abutilon differed from plants of the maleparent selection in the following characteristics:

-   -   1. Plants of the new Abutilon were more freely branching than        plants of the male parent selection.    -   2. Plants of the new Abutilon had smaller and more campanulate        flowers than plants of the male parent selection.

Plants of the new Abutilon can be compared to plants of the Abutiloncultivar, ‘Julia’, not patented. In side-by-side comparisons conductedin Venlo, The Netherlands, plants of the new Abutilon differed fromplants of the cultivar Julia in the following characteristics:

-   -   1. Plants of the new Abutilon were more freely branching than        plants of the cultivar Julia.    -   2. Plants of the new Abutilon had smaller leaves than plants of        the cultivar Julia.    -   3. Plants of the new Abutilon had smaller and more campanulate        flowers than plants of the cultivar Julia.

Plants used for the aformentioned photographs and following descriptionwere about one year old and grown in 10.5-cm containers in aglass-covered greenhouse during the summer in De Kwakel, TheNetherlands. During the production of the plants, day temperaturesranged from 18° C. to 27° C. and night temperatures ranged from 12° C.to 22° C. Plants were pinched one time about six to seven weeks afterplanting.
